I had a house on a grass field for a while. Perhaps it is my somewhat warped (and possibly bent) sense of humor, but I used to enjoy walking up to visitors as they landed with a clipboard and advising them of the $100.00 non-resident landing fee.
....almost got paid once....almost got shot once....almost got run over as they left in a hurry many times.
I'm not sure my special style of humor is universally appreciated.
